don't associate a file with a different package that matches a prefix

What are you trying to accomplish?

Fix #297

What approach did you choose and why?

I think technically we shouldn't do string comparison for this, but the fix was so easy, and swapping in Pathname everywhere quite a bit of work, so I opted for this variant

What should reviewers focus on?

Type of Change

• Bugfix
• New feature
• Non-breaking change (a change that doesn't alter functionality - i.e., code refactor, configs, etc.)

Additional Release Notes

• Breaking change (fix or feature that would cause existing functionality to change)
  This may reattribute files to other packages (the correct packages) and thus add or remove violations.

Checklist

• I have updated the documentation accordingly.
• I have added tests to cover my changes.
• It is safe to rollback this change.
